Astaghfirullah Reminder

A single-purpose Android app that gently reminds you to seek forgiveness (استغفار) with a small heads-up notification every 30 minutes.

أستغفر الله — I seek forgiveness from Allah.

Project Purpose

Reminders can be easy to ignore. This app does exactly one thing: it sends a small pop-up notification saying Astaghfirullah — أستغفر الله every 30 minutes, and nothing else. No counters, no goals, no history, no navigation. You open it, tap Start, and quietly remember Allah throughout your day.

Features

• 30-minute reminders — a heads-up notification with Astaghfirullah / أستغفر الله (high-importance channel, respects Do Not Disturb).
• Start / Stop toggle — one big button. A pulsing gold ring indicates reminders are active.
• Next reminder time — the status card shows the scheduled time (e.g. 11:30 PM), so you know it's working.
• Test Notification — preview the popup immediately instead of waiting 30 minutes.
• Persistent state — reminders stay on after you close the app or restart your phone (WorkManager + DataStore).
• Battery help — an expandable note explaining what to do if a manufacturer's battery optimization delays reminders.
• Light / dark theme — follows the system, using the app's emerald-and-gold Material 3 palette.
• Accessible — every interactive element has a content description for TalkBack.

Architecture Overview

Single-activity Jetpack Compose app with a clean separation between UI, reminders, and data.

MainActivity ──► ui/MainScreen (Compose UI)
        │            │
        ▼            ▼
MainViewModel ◄── data/Prefs (DataStore: running state, next reminder time)
        │
        ▼
reminders/ReminderScheduler ──► WorkManager (PeriodicWorkRequest, 30 min)
        │
        ▼
reminders/ReminderWorker ──► reminders/NotificationHelper (heads-up notification)
        │
        ▼
receiver/BootReceiver  ──► reschedules after device reboot

• WorkManager schedules the periodic work. It is battery-friendly and does not bypass Do Not Disturb. It is intentionally not an exact alarm — a reminder arriving at 30–35 minutes is acceptable and keeps the app Play-Store friendly.
• DataStore Preferences persists the ON/OFF state and the next-reminder display target, so reopening the app shows the real status instead of resetting.
• The Worker updates the next-reminder time after each successful run, so the UI never drifts from what Android actually scheduled.

Build Requirements

• Android Studio (Ladybug or newer) with the Android SDK
• JDK 17 (bundled with Android Studio — JBR — is fine)
• SDK: compileSdk 36, minSdk 26, targetSdk 36
• Gradle 8.11.1 (via the included wrapper)
• Android Gradle Plugin 8.9.1, Kotlin 2.0.21

No Android Studio on the machine? Install it from https://developer.android.com/studio.

How to Run

1. Open Android Studio → Open → select the Astaghfirullah folder.
2. Let Gradle sync finish (it downloads dependencies on first run).
3. Connect your phone with USB debugging enabled (or start an emulator).
4. Press Run ▶ (Shift+F10) and pick your device.
5. Tap Start Reminders and grant the notification permission when prompted.
6. Tap Test Notification to confirm the popup appears.

Building a release APK

./gradlew assembleRelease

The APK is written to app/build/outputs/apk/release/app-release.apk. Release builds are minified (R8) with resource shrinking. Sign it with your own keystore before publishing.
